We think Shakira would be a great fit for the position, considering her international stardom and the amazing stage presence she exudes while performing. However, Twain would be a good pick too, since she has been in the music business nearly two decades now. She is also a successful crossover, with singles like 'Man! I Feel Like a Woman' and 'You're Still the One' appealing to country and pop fans alike.

We have one concern about these two candidates, and that is that both Shakira and Twain are extremely kind-hearted women; so like J. Lo, they may struggle while delivering negative critiques or sending contestants home.

Even though people are buzzing about her replacement, the truth is that Lopez hasn't even confirmed her departure from 'Idol.' Despite this, she may have a hard time balancing her role as a judge on the show along with the other projects she is taking on. Lopez and her husband, Marc Anthony, are getting ready to kick off their own talent show, and she is also up for two film roles. Not to mention that she is also raising two children!
